Attribute and parameter properties

Application class

The application class under which this parameter is displayed.

Command type

Language used to create the command this parameter executes.

Example: PATROL Script Language (PSL)

Icon style

Specifies whether the parameter is represented as a graph, text box, stop light (signal), or boolean state.

Unit

Specifies the unit of measure in which the parameter output is expressed, such as a percentage, a number, or bytes.

Border range

Indicates the normal operating range for the parameter.  The border range must be larger than the Alarm1 and Alarm2 ranges combined.

Values are described as less than and greater than, for example <0 or >100.

If this property is undefined, it means that this property is inactive and any values that appear are not intended as recommendations.

Alarm1 range

Specifies the thresholds for the first-level alarm; this property is not applicable to collector parameters.

Specifies the thresholds for the lower numerical values are deemed unacceptable for this parameter. Values for this property must be lower than values for Alarm2, cannot overlap Alarm2 range, or fall outside the border range. Values falling inside this range trigger warnings, alarms, or recovery actions.

If this property is undefined, Alarm1 is inactive, and any values that appear are not intended as recommendations.

Alarm2 range

Specifies the thresholds for the second-level alarm; this is not applicable to collector parameters.

Specifies the thresholds for the higher numerical values deemed unacceptable for this parameter. Values for this property must be higher than the values for Alarm1, cannot overlap Alarm1 range, or fall outside the border range. Values falling inside this range trigger warnings, alarms, or recovery actions.

If this property is undefined, Alarm2 is inactive, and any values that appear are not intended as recommendations.

Scheduling (poll time)

Specifies how frequently the parameter will run and collect data (polling cycle); this property is not applicable to consumer parameters.

Active at installation

Either  yes or no, specifies whether a parameter is active by default.

Parameter type

Indicates the parameter type:

• Standard parameters gather and display a single data value. Some standard parameters have collector properties.
• Collector parameters gather multiple data values but has no display capabilities.
  
  A PATROL collector parameter executes commands and gathers data for a consumer parameter to display, often collecting many values. It does not display any values itself. As such, it does not have alarms or run any recovery actions. Collector parameters are defined in the collector's application class rather than in the applications for which they collect data. This convention avoids the situation in which a separate collector would execute for each application instance and negate the efficiency of the collector or consumer parameter. 

• Consumer parameters display values gathered by collector or standard parameters.
  
  A consumer parameter only displays a value that is collected by a collector parameter. A consumer parameter never issues commands; it is not scheduled for execution, but it has alarms and can run recovery actions. A consumer parameter cannot be updated directly by selecting an option on its display. To update a consumer parameter, you must execute the collector that gathers its data. For additional information about parameters and defining your own parameters, see the PATROL Console Help or the PATROL documentation for your console. 

Value set by

Lists the collector parameter that sets the values for the consumer parameter described. 

Key Performance Indicator

Monitor for abnormalities

Indicates whether abnormalities should be detected automatically. This applies to all attributes for which alarm ranges have been defined. If you want an attribute to be monitored for abnormalities, you should define the alarm ranges.

Graph

Indicates whether the attribute value should be plotted on the graph by default when Show Graph is selected on the user interface.

Availability

Indicates whether the parameter monitors the availability of the resource.

Response time

Indicates whether the parameter monitors the response time of an action or operation.

Normal distribution

Indicates whether the attribute has data with extreme spikes which makes developing a normal range band difficult.

Statistical

Indicates if the value collected by the attribute is numerical and indicates performance data.
